Struct diem_types::account_state_blob::AccountStateWithProof

pub struct AccountStateWithProof {
    pub version: Version,
    pub blob: Option<AccountStateBlob>,
    pub proof: AccountStateProof,
}

Fields

version: Version

The transaction version at which this account state is seen.

blob: Option<AccountStateBlob>

Blob value representing the account state. If this field is not set, it means the account does not exist.

proof: AccountStateProof

The proof the client can use to authenticate the value.

Implementations

impl AccountStateWithProof

pub fn new( version: Version, blob: Option<AccountStateBlob>, proof: AccountStateProof ) -> Self

Constructor.

pub fn verify( &self, ledger_info: &LedgerInfo, version: Version, address: AccountAddress ) -> Result<()>

Verifies the the account state blob with the proof, both carried by self.

Two things are ensured if no error is raised:

1. This account state exists in the ledger represented by ledger_info.
2. It belongs to account of address and is seen at the time the transaction at version state_version is just committed. To make sure this is the latest state, pass in ledger_info.version() as state_version.

Trait Implementations

impl Arbitrary for AccountStateWithProof

type Parameters = (<u64 as Arbitrary>::Parameters, <Option<AccountStateBlob> as Arbitrary>::Parameters, <AccountStateProof as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<u64 as Arbitrary>::Strategy, <Option<AccountStateBlob> as Arbitrary>::Strategy, <AccountStateProof as Arbitrary>::Strategy), fn(_: (u64, Option<AccountStateBlob>, AccountStateProof)) -> AccountStateWithProof>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for AccountStateWithProof

fn clone(&self) -> AccountStateWithProof

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AccountStateWithProof

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AccountStateWithProof

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<AccountStateWithProof> for AccountStateWithProof

fn eq(&self, other: &AccountStateWithProof) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AccountStateWithProof

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
